Forecast Discussion: Current Conditions as of 1 PM on Friday: An upper level disturbance tracking across the Great Lakes this afternoon is producing some light showers across the region. This system will track south and east tonight and into Saturday before a new storm system develops off the east coast. This new system will bring unseasonably colder conditions for the weekend, but a rebound to near normal temperatures will return early next week. Mostly good air quality is expected over the weekend, but moderate levels could return as early as Monday. *** Saturday’s Forecast: Mostly cloudy conditions are expected on Saturday with the upper level disturbance from Friday now located off to our south and fueling a developing low pressure system off of the east coast. Winds will be breezy as a result of the coastal system intensifying. PM 2.5 concentrations will be held inside the good range due to the dry and clean air that this coastal system will pull into the region as winds become more northerly. There is still limited moisture associated with this system that will only produce some light showers, most likely occurring in the early morning with chances decreasing over the course of the day. Temperatures will be limited to the mid 40s. *** Sunday’s Forecast: Sunday will still be rather windy with strong northerly winds continuing to usher a clean and dry air mass into the region. Mostly cloudy conditions early will become increasingly sunny by the afternoon. Despite increasing sunshine, temperatures will remain below normal and at some of the coldest values we have seen so far this fall. The brisk flow will limit PM 2.5 concentrations to levels well inside the good range. High pressure will begin to build from the west by the late afternoon to evening hours as the coastal system moves further to the north and east. *** Monday’s Forecast: High pressure building over the region for Monday will help temperatures begin to rebound back to near normal values for early November. Winds will turn from northwesterly to more westerly/southwesterly with warmer air moving in aloft. This warm air aloft moving in over colder temperatures near the surface should help PM 2.5 concentrations also begin to rebound. Warmer and more humid air will slowly push into the region, starting early Monday, and the winds will become a bit lighter than they were over the course of the weekend. With quite a clean air mass in place after conditions on Sunday, some locations will take longer than others to see concentrations rise. Concentrations will reach values higher than that of Sunday with low moderate readings expected. Temperatures will return to the low to mid 50s. *** Extended Forecast: High pressure will keep conditions dry and mild on Tuesday before the next cold front approaches for the second half of the week. Temperatures will be back above normal on Tuesday with moisture levels slowly continuing to rise. PM 2.5 concentrations should remain at moderate levels for Tuesday and stay there through at least Wednesday and possibly Thursday. The timing and speed of the cold front over the second half of the week will be key in determining how quickly air quality conditions improve by next weekend. --- Roble
